Art Deco Style Green Chalcedony and Enamel Ring

This item is an Art Deco style ring featuring a prominent rectangular green cabochon stone, likely chalcedony or a similar opaque green gemstone. The central stone is bezel-set within a silver-toned metal mounting. The top of the ring's head has a distinct octagonal or elongated cushion shape, with the center stone surrounded by a band of white enamel. Further detailing includes what appear to be small white or clear stones accenting the corners of the main setting, possibly marcasites or small diamonds, adding a subtle sparkle. On the shoulders of the ring, there are decorative elements resembling stylized leaves or floral motifs, featuring a rich reddish-brown and possibly green enamel, with some areas appearing worn or chipped, particularly the reddish enamel. The metal, given the '10K' context, is likely 10 karat white gold, a common material for jewelry of this period that sought to mimic platinum's appearance. The craftsmanship suggests a manufactured piece rather than a handmade one, with clean lines indicative of the Art Deco period's geometric aesthetics. The condition shows visible wear to the enamel on the shoulders and some surface scratches consistent with use. The central green stone appears intact and smoothly polished. The overall design, with its geometric shape and use of enamel, strongly suggests an Art Deco influence, placing its estimated age typically between the 1920s and 1930s. The ring is worn on a finger, indicating it is of standard wearable size.
